AI Technical Summary

Benefits of technology

The patent describes a method for coloring hair with reduced skin staining. The method involves applying a coloring agent to the hair, allowing it to act for a certain period of time, and then applying a cleaning agent to the skin areas that may come into contact with the coloring agent. The cleaning agent includes an anionic surfactant. The method also includes using a multicomponent packaging unit comprising an aqueous coloring agent and an aqueous cleaning agent, which differ in pH by at least one unit. This difference in pH helps to reduce skin staining during coloring.

Problems solved by technology

Oxidation dyes are notable for outstanding, long-lasting color results, but are also associated to a certain degree with hair damage.
If, in contrast, the amount included in the coloring product is designed for multiple use, providing several pairs of gloves is neither an economically viable nor a lasting solution.
Lastly, there are also application forms that make the wearing of gloves impractical during single use as well.
Wearing gloves in the shower also does not appear to be very convenient for the user.

[0215]A multicomponent packaging unit includes

50 g of coloring agent (F) and

150 g of cleaning agent (R).

[0216]The multicomponent packaging unit includes the agents (F) and (R) in a weight ratio of 1:3.

[0217]In a very particularly preferred embodiment, the multicomponent packaging unit of the invention is characterized in that it includes the coloring agent (F) and the cleaning agent (R) in a weight ratio (F) / (R) of 1:1 to 1:10, preferably of 1:1 to 1:5, more preferably of 1:2 to 1:5, and very particularly preferably of 1:3 to 1:5.

[0218]The coloring agent (F) and the cleaning agent (R) are provided preferably as a liquid, in particular as an aqueous preparation.

[0219]At least one surface-active substance can be added in addition to the coloring agent (F), wherein such surface-active substances are called surfactants or emulsifiers depending on the field of application: They are preferably selected from anionic, zwitterionic, amphoteric, and nonionic surfactants and emulsifiers.

Abstract

A method for reducing skin staining during the coloring of hair includes the following steps in the indicated sequence:A1) applying a coloring agent (F) to the hair,A2) allowing the coloring agent (F) to act for a time period from 30 seconds to 45 minutes,B1) applying an undiluted cleaning agent (R) to skin areas that can come into contact with the coloring agent (F) when the latter is washed out,C1) jointly washing out the coloring agent (F) and cleaning agent (R),whereinthe coloring agent (F) includes at least one oxidation dye precursor and / or at least one direct dye andthe cleaning agent (R) includes at least one anionic surfactant.A multicomponent packaging unit includes the coloring agent (F) and the cleaning agent (R).

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to cosmetics, and more particularly relates to a method that enables coloring of hair with reduced skin staining.[0002]The present invention also generally relates to a multicomponent packaging unit (kit of parts), which comprises a suitable coloring agent and cleaning agent.BACKGROUND OF THE INVENTION[0003]The changing of the shape and color of hair is an important field in modern cosmetics. Because of this, the appearance of the hair can be adapted both to current fashion trends and to the individual wishes of the particular person. To change the hair color, the skilled artisan is familiar with a variety of coloring system depending on the coloring requirements. Oxidation dyes are typically used for permanent, intense dyeing with good fastness properties and good gray coverage. Such coloring agents typically include oxidation dye precursors, so-called developer components and coupler components, which together for...
